Method for automatic closed-loop control of one or more combustion temperatures in a gas turbine installation and method for determination of the water content in the working fluid of a gas turbine installation

摘要

The invention relates to a method for automatic closed-loop control of one or more combustion temperatures in a gas turbine installation, having the following steps: measurement of a plurality of temperatures of the working fluid of the gas turbine installation at various positions in the gas turbine installation, measurement of a plurality of pressures of the working fluid at different positions in the gas turbine installation, determination of the water content of the working fluid flowing through the gas turbine installation, taking account of the measured values, and setting of at least one combustion temperature for the gas turbine installation as a function of the determined water content.
